Manufacturer of aftermarket ECUs

General Information


The Emerald is plug and play with non VCC MEMS cars.

S2 (K-series)

No commercial adaptor loom is available at the moment. Emerald are working on a 'solution' at the moment but it is as of yet not ready. So basically the loom needs to be chopped and the new emerald plug wired onto the end. Also, the standard S2 IACV (Idle Air Control Valve) will NOT work with the Emerald (the ECU can't drive it). If you require the IACV then you'll need one from an S1, these are available from Eliseparts.
